Title: Millimeter wave oscillator
Inventor: DOMOTO CHIAKI
IPC: H03B9/12
Filed: 2003-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that, in a millimeter wave oscillator in which a Gunn diode element is mounted on a millimeter wave resonator substrate, a semiconductor substrate which constitutes the Gunn diode has a bad heat dissipation property, increases the temperature of a Gunn diode active layer during operation and thereby remarkably reduces the millimeter wave output.  <P>SOLUTION: The millimeter wave oscillator has such a structure that a thin film Gunn diode element 1 formed by stacking first n<SP>+</SP>-type layer and n-type layer and a second n<SP>+</SP>-type layer, each of which is formed of a thin film semiconductor, in this order, is mounted on the resonator substrate which is such that a resonator (signal electrode 3 and ground electrode 4) formed of a metal layer is formed on a top face of a dielectric substrate 2. By separating the semiconductor substrate having a bad thermal conductivity from the Gunn diode, heat generated by the Gunn diode active layer of the thin film Gunn diode element 1 can be easily dissipated to the millimeter wave resonator substrate side, resulting in the suppression in rise in temperature of the Gunn diode and subsequent stabilization of millimeter wave output strength.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Smoking tool equipped with mechanism that can practically suppress sidestream smoke from tobacco smokes
Inventor: HAMAZAKI SUMIHIRO
IPC: A24D1/10
Filed: 2003-06-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a new type of smoking tool that can simply suppress the sidestream of tobacco smoke that has high hazard and bothers the people in vicinity although there has been many tools that are used by mounting it to a tobacco body.  <P>SOLUTION: In the view that the sidestream smoke occurs from the outside part of the tobacco, burning position and a nonflammable or flame-retardant water or solution is applied to the outside part except the inside burning part (3) to form an air-impermeable coating film part (4). Thus, the air-impermeable coating film part (4) does not burn and only the inner burning part (3) burns, whereby the sidestream smoke is scarcely formed and only the main smoke flow is generated. On the basis of this idea, several smoking tools can readily be embodied. In this case, the tobacco becomes extinguishable after twice or thrice smoking. But, when the burnt part is cut off, the remaining part can be smoked in the similar way whereby the tobacco expenditure can be largely saved with wasted part minimized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
